Four scenarios train judgment with numbers. Each states its assumptions, shows its arithmetic, and ends with a recommendation.

Flow from cost estimation through agent design and context fitting to evaluation.

The four scenarios in teaching order: cost, agent design, large context, and evaluation.

Lesson	What it covers
Estimate a Review Assistant Budget	Monthly token cost of a code-review assistant from example parameters.
Design a Regression-Triage Agent	Agent scope, guardrails, time saved, and a three-step chain estimate.
Give a Model a 300k-Token Codebase	Why full pastes fail, retrieval instead, and a cost comparison.
Evaluate Before Adopting a Tool	A golden set, a rubric, a pre-set bar, and worked scoring.

Check yourself Why does every scenario here state example parameters instead of real prices?

Real prices and model limits change across vendors and over time. Stated example parameters keep the arithmetic checkable without stating facts that expire.
